CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 234,111, dated November2, 1880. Application filed October 2, 1880. (ModeL) To all whom it mayconcern:

Be it known that I, DANIEL KEETHLER, of Mount Orab, in the county ofBrown and State of Ohio, have invented. a new and useful Improvement inCar-Couplings; and I do hereby declare that thefollowin g is a full,clear, and

exact description of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, forming a partof this specification, in which- Figure 1 is a sectional elevation ofthe coupling, showing the lid in section and in dotted lines. Fig. 2 isa plan of the coupling with lid removed. Fig. 3 is a front elevation ofthe lid.

My invention has for its object to provide a coupling which will coupleitself, and in case a car is thrown from the track by accident it canconveniently uncouple itself; and the nature of my invention consists inthe novel construction and arrangement of the several parts hereinaftermore fully described.

Referring to the drawings, A is the bufferhead,'which is made so as toform a part of the connection, or that portion to which the car isattached, each side of said buffer-head describing a curve from thefront portion thereof to the rear at its top, the inner sides of thesame being so beveled off that it may admit of the link being removedfrom the pin. Extending from the front or face of the bufferhead, and onthe bottom of the same, and be tween the sides thereof, is cut aninclined surface, a, terminating near about midway the opening.

B is a steel pin, oval in cross-section, and having a reduced portion,1), which fits in a corresponding opening in the bottom of thebuffer-head. This pin is beveled on its front face, and forms, with theincline a of the bufferhead, a continuous surface to guide the link whenit enters.

0 is a lid, which covers the opening in the buffer-head, and is providedwith an incline surface on its under side to assist in guiding the link.The lid is also provided with a recess, c, which fits over the top ofthe pin and affords a support to the pin, and enables it to resist thestrain to which it is subjected in use. The buffer-head is provided withgrooves D D, into which the draw-straps are fitted, and whichdraw-straps are attached to the frame-work of the car in the ordinarymanner.

E is a slot in the buffer-head into which fits the tongue 0 of thelid G.The lid is pivoted in the slot by the fulcrum-pin c in such a mannerthat it may be raised sufficiently to allow the link to be removed fromthe pin in uncoupling, as shown in dotted lines in Fig. 1.

F is the coupling-link, shown in dotted lines in the same figure.

The operation of my invention is as follows: In the backing of one caragainst the other which is connected by the link the link is raised upthe double incline, which is formed by the bevel of the buffer-head andpin, to a sufficient height to raise the lid and allow the link to passover the top of the pin, and thus couple the car; and if the car, byaccident, should be thrown from the track, the link will gradually riseup the inclined surfaces of the buffer-head and pin to the top, and overthe pin and curved sides, raising the lid simultaneously therewith, thusuncoupling the car, said link falling over and out to one side of thebuffer-head.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The buffer-head A, having secured therein the steel pin B, incombination with the pivoted lid 0, having the recess 0, adapted toclose down over the top of pin B and afford a support to the same,substantially as herein described.

In testimony whereof I affix my signature in presence of two witnesses.
